Title: Manufacture of cadmium anode plate for alkaline storage battery
Inventor: SHIMODA MASAKAZU
IPC: H01M4/29
Filed: 1983-03-29
Abstract: PURPOSE:To provide cadmium anode plate in which active material strongly adheres to core material, for an alkaline storage battery by applying cadmium plating on conductive core material and oxidizing the plating surface, then coating it with paste mainly comprising CdO. CONSTITUTION:Cadmium plating is applied on core material comprising conductive porous thin plate and the surface of the plating layer is oxidized to form CdO, Cd(OH)2 layer. The core material is coated with paste mainly comprising CdO and they are dried and provided with formation. By this process, CdO layer of the core material and a part of CdO of active material are reduced, and the network of metallic Cd is formed.

IPC: G11B5/23
Filed: 1989-03-07
Abstract: PURPOSE:To suppress a so-called shape effect and to decrease waviness in reproduced output-frequency characteristics by forming chromium nitride films on the gap-facing surfaces of cores consisting of oxide magnetic materials and forming chromium films between the chromium nitride films and thin alloy magnetic films. CONSTITUTION:The chromium nitride films 4 are formed on the gap-facing surfaces of the cores 1', 2' consisting of the oxide magnetic materials and the chromium films 9 are formed between the chromium nitride films 4 and the thin alloy magnetic films 5. The interdiffusion of oxygen, etc., between the thin alloy magnetic films 5 and the cores 1', 2' consisting of the oxide magnetic materials is suppressed by the chromium nitride 4 formed on the gap-facing surfaces. The deterioration in the soft magnetic characteristics of the cores 1', 2' and the thin films 5 near the boundaries of the cores 1', 2' and the thin films 5 is, therefore, prevented and the parts where the soft magnetic characteristics are deteriorated are thereby prevented from acting again as the gap at the time of reproduction. The shape effect is suppressed in this way and the waviness in the reproduced output-frequency characteristics is decreased.

Abstract: PROBLEM TO BE SOLVED: To realize space diversity by having only to provide one system of an antenna and a receiver and having only to assign one spread code, in a mobile communication unit without the need for provision of two systems of antennas and receivers. SOLUTION: In this radio communication system, a delay section 3 delays a spread signal with a delay amount τ, in response to a period of decrease in a reception electric field in a mobile communication unit caused due to fading, and an adder 9 sums the spread signals which are not delayed and the delay signal and the sum is transmitted. When the mobile communication unit moves, there is a fluctuation in a received electric field strength which is called as a 'median fluctuation' and an 'instantaneous fluctuation' due to its moving propagation characteristics, even of the received wave strength at a time t1 rapidly fails off due to the median fluctuation or the instantaneous fluctuation, since the data are retranmitted at a time t=t1+τ with the delay τ, the decrease in the electric filed strength can be supplemented.
